Description
STB6100
The STB6100 ASIC is a highly integrated, low-cost direct conversion (zero IF) tuner IC for
DVB-S2 broadcast satellite applications.
This device includes an LNA, down-converting mixers, baseband low-pass filters, gain
control, on-chip VCO and a low noise PLL. Its wide gain control range is well suited for low
symbol rate applications.
The STB6100 is controlled by a simple two-wire interface and has been designed to
minimize the external bill of materials to reduce manufacturing costs and to simplify the
board layout. The reduced component count ensures greater system reliability leading to
increase consumer satisfaction.
The DVB-S2 standard increases the capacity of satellite broadcasts by as much as 30%, so
enabling the effective deployment of high data rate applications such as high definition TV
and broadband internet. Packaged in VFQFPN2 5x5x1.0 32 pitch 0.50 package, it is ideal
for low cost DBS design.
